EN 1.4313 ( DIN X3CrNiMo13-4 ), F6NM stainless steel round bars
EN 1.4313, DIN X3CrNiMo13-4, AISI F6NM, UNS S41500 is a 13% Cr-4% Ni-0.5% Mo martensitic stainless steel. Its nickel content, associated with low carbon ensures better weldability, ductility,
impact and fatigue resistance than 13 Cr martensitic grades (410, 420).
The alloy has good corrosion resistance to fresh water and performs well in abrasive conditions.
It combines high mechanical properties, excellent toughness and weldability.
It is commonly used in turbines and flow control systems in the hydropower industries.
